To all 'whom z't may concern:

Be it known that we, GoMnn vW. PRICE and CURT F. ZIMANsKY, citizens ofthe United States, residing in the city and` county of 6 SanFrancisco'andState of California, have invented a new and usefulImprovement in an Antisand Bearing, of which the followin isa'speciiication.

r invention relates to improvements in l shaft bearings for rotary wellpum s and the like wherein means are provi ed for reventing the entranceof sand into `the aring. i The primary object of our invention is toprovide any improved pump shaft bear nother object is to reduce wear on`a pump shaft bypreventin the entrance of' sand from water pumpe lintethe shaft bearings within the pump.

A further object is to circulate vwater around a pump shaft bearing tocarry sand suspended inthe water away from the bearm Ve accomplish theseand other obgects by means of the device disclosed in the drawingsforming a tion -wherein like characters of reference are used todesignate similar parts throughout said specification and drawings and1n which: Figs. 1 and 1l are broken side elevations of a well bearing.

-F ig. 2 is a broken vertical sectionof the pump on a larger scaledisclosing our'invention applied thereto.

Fig. 3 isa view similar to Fig. 2 disclosing the application of ourimproved bear- 4 ing to a pumplhaving a runner of another .ferrin tothe' drawingsthe numeral 1 l part of the present specificapump andcasings parts being` l broken away and shown in section to dis-` 35close the application of our improved shaft bearing, within the reduceded. at in- Number 471,460, May' 21, 1921 and. form 55. no part of thepresent invention. .The shaft y 4 is provided at the top thereof with apulle 8 arranged to vbe driven from any. suita le source of power in theusual manner. i 00 The pump 1 comprises a plurality of bowls 11 havingan inner wall 12 and an outer wall 14 connected in spaced relation byvertically disposed connecting webs 16 farming water assages117therebetween.' 05 Runners or impe ers 18 are mounted upon,y the shaft 4within' the bowls 11, :said-runners 18 having webs or venes 19 adaptedto. force water upwardly into the water pasf sages 17 when the shaft bisrotated.v Bear- 70 ings 21 are provided in the bowls 114 to receive theshaft 4 and hold the same in alignmene `In the present'state of the artthe bearings are cast as an integral part of the bowl, the '75 .bearingbeing' connected with an inwardly projecting continuation of the u perorl tion of the inner wall of the bow the. ow" er portion ofthe bearingAbeing connected the lower portionof'tlie inner wall/by a '8 0 continuousweb. The water within the well usuall carries sand and sediment in asuspended condition due tothe operation of the runners in agita'tingvand elevating the water. 'As the water passes upfwardly from 85 thelowermost bowls of the pump .to receive further upward impetus from therotating varies ofthe next. runner above an eddy due to the change indirection of ow of water is caused adjacent the upperend of thepressiireareaA f at the central-portion of the runner. The reducedpressure adjacent the bearing andthe eddy current formed therein co-'actto cause; sand and sediment carried by the pas 95 ing water to becollected upon the uppermost end of the bearing,.the continuous ro-vtation ofthe shaft causing a portion of such sand and sediment to enterthe beai' ing with obviouswdamage by abrasion to 1 both the shaft andthe bear'ng.;

To prevent sand and sediment from working into the bearing 21 vwe haveprovided "a bearing formed separate] from the bc'wl.I The bearing 21 islprovid bearing arranged to be engaged by and 'suitably secured toashoulder26formed upon with aniinnlar* u ange 24 adjacent the lower endof said the lower end of the inner wall 12 of the bowl. The upperportion 22 of the wall 12 lis bored larger than the diameter of theshaft 4 above the bearing 21 as best disclosed in Figs. 2 and 3 of thedrawings, a chamber 27 being formed by the wall 12 and the flange 24 toenclose the bearing 21. The flange 24 is'provided with a plurality ofoutlet apertures 28 adjacent the bearing 21. The runners 18 are mountedimmediately below the bearing 21 so that the vanes 19 will operate inthe portion of the bowl 11 immediately below the flange 24. Rota-- tionof the runners 18 causes a reduced pressure area to be formed at theinner end of the vanes 19, this reduced pressure creating a suctionoperating to draw water to replace that displaced fromin front of thevanes 19, this suction operating to draw water from the chamber 27through the apertures 28. In this manner a downward circulation of wateris caused in the chamber 27 and all sand and sediment Working into theupper end 22 of the wall 12 is carried past the top of the bearing 21and discharged through the apertures 28 thereby keeping the bearing freefrom foreign material carried in the water. The portion 22 of the wall12 is made to allow suflicient clearance for the shaft 4 to-permitfree'passage. of sand and sediment therethrough and into the chamber 27without damaging the shaft by abrasion.

An annular flange 30, having the outer portion thereof downwardlyinclined, is

mounted upon the shaft 4 immediately above the bearing 21 to furtherdeflect sand and sediment away from the bearing and into the chamber 27,thereby assisting the circulation above describe in preventing theentrance of such lsand into the bearing.

The sand discharged from the apertures 28 passes back into the pumpthrough apertures 31 (provided in the flan ed type of runner 18 isclosedin Fig. 2. en a runner 18 of the type disclosed in Fig. 3 of thedrawings is used no aperture 31 is necessary as the sand works outthrough the clearance at the outer rim of the runner.

Having thus described our invention that we claim4 as new and desire tosecure by Letters Patent is: i

1. The combination with a rotary well pump provided with bowls havingwater passages, a shaft and runners mounted therein, of a bearingmounted withiny each bowl to receive said shaft; and a suction chamberenclosinglaid bearing and arranged to cause sand a itted into saidchamber above said bearing to be drawn awa from said bearing by suctioncreated within the chamber when the runners are operated.l n

2. The combination with a rotary .wel

3. The combination with a rotary well having water assages, a shaft andrunners therein, of a earing mounted -within each bowl of the pump toreceive the shaft; and a chamber formed within each bowl and enclosingsaid bearing and provided with an upper passage surrounding said shaftand outlet apertures inthe bottom of said chamber communicating with theassages of the bowl whereby rotation of said Arunners will produce asuction and circulation through said chamber to carry water andsuspended sand through said chamber and away from the bearing therein.
